And each of you ¹  take his censer, put ²  incense in it, and then each of you present his censer before the Lord: 250 censers, along with you, and Aaron – each of you with his censer.”

So everyone took his censer, put fire in it, and set incense on it, and stood at the entrance of the tent of meeting, with Moses and Aaron.

Then ¹  Aaron’s sons, Nadab and Abihu, each took his fire pan and put fire in it, set incense on it, and presented strange fire ²  before the Lord, which he had not commanded them to do.
